Thanks gold_finger for the reply,
In the path you have mentioned have found an option "Enable automatic mounting of removable media" which was disabled. Enabled it and also enabled other two options to "mount all removable media at login" and "automatically mount removable media when attached" and another one kept disabled to automatically mount only those removable medias which were mounted manually before. Also checked all "disconnected devices" to "Automount on attach".

Unfortunately still my flash drives are not mounting automatically.

For bluetooth I think I should go to hardware service centre. May be some hardware switch has been turned off inside. But still any other way to check for it will be helpful.

I have checked for all setting option of Dolphin. Can't understand why external drives are not showing up?

Since you haven't gotten an answer yet, I'll give it a shot. Not a KDE user but have KDE15 in VirtualBox and am guessing 16 works similarly.

Have you gone to Menu -> Computer -> System Settings -> Hardware -> Removable Devices? You can set how you want the system to handle mounting USBs and external drives there.

Under same "Hardware" heading, open "Driver Manager" and see if something shows up for your Bluetooth.

If these were disabled before, go ahead and enable them. If no immediate effect, reboot system and see if attaching a USB now works and if Dolphin now shows external drive(s).

Please add [SOLVED] to your thread if a solution is found. Go to your first post in the thread, hit "Edit" button and add [SOLVED] to the title of the post.

I did enable it even before you told me to do. At first it did not worked though I restarted my computer.
Now it is working fine. All USB Flash drives are getting mounted automatically. And Dolphin showing up all external drives now.
I have no idea how did it happened. A small system update was there. I think that may have solved the issue.

Thanks for the help gold_finger.
